Yamnaya ancestry (Indo-European steppe-pastoralists) make up a large percentage of European genetic ancestry. Modern Europeans are a mixture of three ancestral populations: steppe-pastoralists from the east (Yamnaya...), Western huntergathers, and Anatolian farmers. In some Northern Europeans, the fraction of farmer ancestry may be less a minority.
“Yamnaya–related ancestry is found in the DNA of modern Central, and Northern Europeans (c. 38.8–50.4 %), and is also found in lower levels in present-day Southern Europeans (c. 18.5–32.6 %), Sardinians (c. 2.4–7.1 %), and Sicilians (c. 5.9–11.6 %).[80][71][13]”
